There is no silver bullet to deal with disease in any given crop. But we can recommend an integrated pest management approach in every case. This includes physical, cultural, biological and chemical control. Ensure you’ve chosen the right control measures for the disease, and make sure to get your timing and coverage right. We’ve chosen some of the top disease challenges you’re likely to face in canola, pulses, and cereals and have paired them with our best recommendations for control. *Always read and follow label directions.

Top Fungicides
Priaxor®
Groups 7,11
Active Ingredient: Fluxapyroxad, Pyraclostrobin
Apply at the 2-6 leaf stage. Scout early and often for blackleg, especially in warm, humid conditions. Look at 50 plants in a W pattern through the field and apply fungicide to suppress the disease if lesions are found on more than 10% of plants. Earlier timing has the greatest chance of reducing the incidence of the disease.
Quilt®
Groups 3,11
Active Ingredient: Azoxystrobin, Propiconazole
Apply at the 2 leadf to bolting stage. Scout early and often for blackleg, especially in warm, humid conditions. Look at 50 plants in a W pattern through the field and apply fungicide to suppress the disease if lesions are found on more than 10% of plants. Earlier timing has the greatest chance of reducing the incidence of the disease.
Top Fungicides
Proline® 480 SC
Group 3
Active ingredient: Prothioconazole
Apply at 20-50% flower. Ideal fungicide spray timing is at 30% bloom to soak the maximum number of petals before they drop.
Cotegra®
Groups 3,7
Active ingredient: Boscalid, Prothioconazole
Apply at 20-50% flower. Ideal fungicide spray timing is at 30% bloom to soak the maximum number of petals before they drop. Consider a second pass in 7 to 14 days after first application if you: 1. Have a crop worth protecting with high yield potential. 2. See continued high disease pressure. 3. Have a history of sclerotinia. 4. Seeded into stubble of a susceptible crop or rotations are tight.
Lance® AG
Groups 7,11
Active ingredient: Boscalid
Apply at 20-50% flower. Ideal fungicide spray timing is at 30% bloom to soak the maximum number of petals before they drop. Consider a second pass in 7 to 14 days after first application if you: 1. Have a crop worth protecting with high yield potential. 2. See continued high disease pressure. 3. Have a history of sclerotinia. 4. Seeded into stubble of a susceptible crop or rotations are tight.

Prosaro® XTR
Group 3
Active ingredient: Prothioconazole, Tebuconazole
For suppression of FHB in wheat apply when at least 75% of the wheat heads on main stems are fully emerged to when 50% of the heads on the main stem are in flower. Optimal timing for fungicide is when flowering begins and you can see yellow anthers in the middle of wheat heads.
Caramba®
Group 3
Active ingredient: Metconazole
For suppression of FHB in wheat apply when at least 75% of the wheat heads on main stems are fully emerged to when 50% of the heads on the main stem are in flower. Optimal timing for fungicide is when flowering begins and you can see yellow anthers in the middle of wheat heads.
Miravis® Ace
Groups 3,7
Active ingredient: Propiconazole, Pydiflumetofen
For suppression of FHB in wheat (spring, winter, durum) apply when at least 75% of the wheat heads on main stems are fully emerged to when 50% of the heads on the main stem are in flower. Optimal timing for fungicide is when flowering begins and you can see yellow anthers in the middle of wheat heads.
Top Fungicides
Nexicor™
Groups 3,7,11
Active ingredient: Fluxapyroxad, Pyraclostrobin, Propiconazole
Nexicor can be applied to manage tan spot in wheat from stem elongation until early head emergence. We recommend you apply at flag leaf. Fungicides don’t have much curative action and are only effective when you follow the label and spray at the correct stage to provide the best protection against cereal leaf diseases.
Trivapro®
Active ingredient: Solatenol, Azoxystrobin, Propiconazole
Apply Trivapro in cereals (barley, wheat, oats) between stem elongation and head half emergence up until the flag leaf stage. We recommend applying at flag leaf. Fungicides don’t have much curative action and are only effective when you follow the label and spray at the correct stage to provide the best protection against cereal leaf diseases.
Quilt®
Active ingredient: Azoxystrobin, Propiconazole
Apply Quilt in cereals at early flag leaf stage to protect the flag leaf from a number of leaf diseases that can reduce grain quality and yield. Fungicides don’t have much curative action and are only effective when you follow the label and spray at the correct stage to provide the best protection against cereal leaf diseases.

Priaxor®
Groups 7,11
Active ingredient: Fluxapyroxad, Pyraclostrobin
Apply in lentils at a rate of 80 acres per jug at the onset of symptoms and up to the beginning of flowering. You are at higher risk of encountering resistance if you rotate pulse crops every two-three years, if you always use Group 11 fungicides, if you cut fungicide rates, if you have neighbouring fields with confirmed resistance, or if you’ve had high anthracnose pressure in previous years.
Dyax®
Active ingredient: Fluxapyroxad, Pyraclostrobin
Apply in lentils at a rate of 60 acres per jug at the onset of symptoms and up to the beginning of flowering.

Intego® Solo (seed treatment)
Acitve ingredient: Ethaboxam
Intego Solo will only control early season infection. The plant will be susceptible after the seed treatment has worn off later in the season. Lengthen rotation between host crops and avoid planting peas on heavier pieces of land. Try to eliminate any reason for standing water or poor water movement in the soil.
